There are still many causes of hematospermia in the elderly. Common causes: the first is medical trauma, more common like prostate biopsy surgery, biopsy after some patients may appear hematospermia. There is also prostate removal surgery, transurethral resection of the prostate can also appear blood semen. The second is that inflammation of the seminal vesicles or prostate can cause hematospermia, which is also relatively common. Some people may develop tuberculosis of the seminal vesicles, or even tuberculosis infection of the prostate, which can also result in hematospermia. Some patients have stones in the prostate and seminal vesicles, which can cause hematospermia over time. The third type is malignant tumors of the genitourinary tract, tumors of the bladder, and tumors of the prostate, testicles and seminal vesicles can cause hematospermia. So if there is hematospermia, it needs to be taken seriously. The fourth type is systemic diseases, such as abnormal blood clotting function, some older people need to take anticoagulant drugs, and after taking the drugs there are problems with blood clotting function, then blood sperm will appear. Another kind is that some people are older, but the frequency of sexual life is higher, so the sexual life is more excessive, once a day or even more, or suddenly interrupt the sexual intercourse will also appear blood semen.
